Environment Southland will hold a briefing with rural representatives and environmental groups today to discuss the impact of the prolonged dry spell.

Despite patchy rainfall throughout Southland at the weekend, river flows and several aquifers are still at significantly low levels, and groundwater and moisture levels barely registered change.

MetService duty forecaster John Law said about 2 millimetres of rain was recorded at Gore, 5mm at Invercargill and 12mm at Lumsden during the weekend and, apart from a few scattered coastal showers, the region would remain dry until the weekend.

A front forecast for Saturday was expected to bring showers to Southland, but it was not yet known how heavy they would be, he said.
